Did you at least scrub the corrosion off the connector with a wire brush? Depending on how bad its crusted on it could be part of your problem.
You should also just swap the battery for a new one under warranty if you dont want to pay the dealer. <- You shouldnt.

I didn't:$ it was 90% covered by some orange oxide. Although, it's been like that for the past year without any problem. This started AFTER I replaced the battery. I will try to talk to Canadian Tire, after the dealership replaces the alternator. However, I think they might deny my claim since the battery is practically new.

Well, the reason they probably wont trickle charge it for you is they 1. might not have one 2. make more money from you buying a battery 3. its too much trouble.

Honestly, I'd say just return it and swap for a new one. Same difference.

Its also possible is that the corrosion and the subsequent killing of your battery is also how your alternator died.

The dealer will check the battery and the alternator. If the result shows that both are bad, they will replace both. If the battery is still good, they will trickle charge it. I know your battery is new, however, the bad alternator can kill a brand new battery.

Op your title is stupid.

You have a bad alternator, connection or a fault draining your battery.

After 8 years a battery owes you nothing.

If you're making a lot of short trips, blasting music with your heated seats on; the car will have a tough time keeping the battery charged.

Ok got it, it just seems odd that the alternator goes out right after the battery replacement. The old battery didn't hold up charge well, but it never led to loss of power steering, illuminated lights, loss of power to interior electronics while driving before.

Nevertheless, it would need to be jumped sometimes if the trip taken was too short.

Thanks for the input, title has been changed

I used to have a 2003 Toyota with 130k miles and the oem alternator still worked when I got rid of it. This is350 has 62k.

I thought they were reliable to.In 3 years battery died, headlights out, piston rebuild for rattle, rear boot went, navi frozen replaced, water pump went, radiator went, rear calipers frozen and now getting code for camshaft sensor bank B. Car is very well maintained as well. Sorry for hi-jacking post .

Reliability is a term used in aggregate to describe the overall group performance. Everything has a probability function so there is no perfect information in the real world and according to all the reports, Lexus is reliable. There will always be cars that fall below or above. Btw did you buy the car used?

Yea I know there reliable that's why I bought one was venting a little. I love my IS and would get another one. I bought it used 4 years ago. Never left me stranded.

Seems like a lot of bad alternator stories popping up here lately. This will tend to happen going into the winter months too when the vehicle even that much more relies on the batteries CCAs.

Monday Night Update: Car was towed to dealer on Saturday, as normal service charged one hour labour to diagnose the problem. But as of now they still haven't gotta a chance to touch the car yet...

I thought all they have to do is just use a voltmeter to test the alternator/battery..Should have gotten it towed to a moms & pa garage..

For "minor" repairs/replacements it is much cheaper to have the work done at a local shop. Reason why I have a friend with his own shop; he gets all of my random business that I don't have the tools/machines for or a lift.

Thanks guys! Just got the car back from Lexus.

I would totally get an independent garage to do work on my car, but there is no lexus specialist around my area, except for the lexus dealership. The dealership is excellent in my opinion, and they charge a very fair "dealership price". Maybe when i finish school and move to a bigger city like Toronto, then I will find one.

Total damage is $700. I though Christmas is still a month away.
